# Components:

→ Meat Filling

01 - 1 lb ground lamb
02 - 1 medium onion, finely chopped
03 - 2 medium carrots, diced
04 - 2 celery stalks, diced
05 - 2 cloves garlic, minced
06 - 1 cup frozen peas
07 - 2 tbsp tomato paste
08 - 1 cup beef or vegetable broth
09 - 1 tbsp Worcestershire sauce
10 - 1 tsp fresh thyme leaves
11 - 1 tsp fresh rosemary, finely chopped
12 - ½ tsp salt
13 - ¼ tsp black pepper
14 - 2 tbsp olive oil

→ Cauliflower Mash Topping

15 - 1 large head cauliflower, cut into florets
16 - 2 tbsp butter
17 - ¼ cup milk
18 - ¼ cup grated Parmesan cheese
19 - ½ tsp salt
20 - ¼ tsp ground white pepper

# Method:

01 - Preheat oven to 400°F
02 - Bring a large pot of salted water to a boil. Add cauliflower florets and cook until very tender, approximately 10-12 minutes. Drain well and set aside.
03 - While the cauliflower cooks, heat olive oil in a large skillet over medium heat. Add onion, carrot, and celery; sauté until softened, approximately 5 minutes.
04 - Add garlic and ground lamb to the skillet. Cook, breaking up the meat, until browned and cooked through, approximately 5-7 minutes.
05 - Stir in tomato paste, Worcestershire sauce, thyme, rosemary, salt, and pepper. Cook for 1 minute.
06 - Add broth and peas. Simmer uncovered, stirring occasionally, until slightly thickened, approximately 8-10 minutes.
07 - Transfer the drained cauliflower to a food processor. Add butter, milk, Parmesan, salt, and white pepper. Blend until very smooth and creamy.
08 - Spoon meat filling into a 2-quart baking dish and spread evenly. Top with the cauliflower mash, smoothing the surface with a spatula.
09 - Use a fork to create decorative ridges in the mash.
10 - Bake in the preheated oven for 20 minutes, or until the topping is golden and filling is bubbling.
11 - Let rest for 5 minutes before serving.

# Expert Advice:

01 -
  • It tastes like the shepherd's pie you grew up with, but without the post-meal heaviness that usually follows.
  • Ground lamb develops this incredible umami depth when paired with thyme and rosemary, and somehow the cauliflower mash just lets it shine instead of competing.
02 -
  • Drain that cauliflower aggressively after cooking—any water trapped in there will weep into your mash and turn it watery and sad.
  • Don't skip the resting time, not because it's fancy but because it lets the filling firm up just enough that your first spoonful actually holds together.
03 -
  • For extra visual appeal and flavor, sprinkle a little grated cheddar across the top before baking so it melts into golden, savory patches.
  • If your food processor isn't powerful enough to make the cauliflower completely smooth, a potato masher works—you'll just get a slightly chunkier, equally delicious texture.
